Method Details
-
getNamedItem
Retrieves a node specified by name.- Specified by:
getNamedItem
in interfaceNamedNodeMap
- Parameters:
name
- ThenodeName
of a node to retrieve.- Returns:
- A
Node
(of any type) with the specifiednodeName
, ornull
if it does not identify any node in this map.
-
setNamedItem
Adds a node using itsnodeName
attribute. If a node with that name is already present in this map, it is replaced by the new one.
As thenodeName
attribute is used to derive the name which the node must be stored under, multiple nodes of certain types (those that have a "special" string value) cannot be stored as the names would clash. This is seen as preferable to allowing nodes to be aliased.- Specified by:
setNamedItem
in interfaceNamedNodeMap
- Parameters:
arg
- A node to store in this map. The node will later be accessible using the value of itsnodeName
attribute.- Returns:
- If the new
Node
replaces an existing node the replacedNode
is returned, otherwisenull
is returned. - Throws:
DOMException
- WRONG_DOCUMENT_ERR: Raised ifarg
was created from a different document than the one that created this map.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly.
INUSE_ATTRIBUTE_ERR: Raised ifarg
is anAttr
that is already an attribute of anotherElement
object. The DOM user must explicitly cloneAttr
nodes to re-use them in other elements.
HIERARCHY_REQUEST_ERR: Raised if an attempt is made to add a node doesn't belong in this NamedNodeMap. Examples would include trying to insert something other than an Attr node into an Element's map of attributes, or a non-Entity node into the DocumentType's map of Entities.
-
removeNamedItem
Removes a node specified by name. When this map contains the attributes attached to an element, if the removed attribute is known to have a default value, an attribute immediately appears containing the default value as well as the corresponding namespace URI, local name, and prefix when applicable.- Specified by:
removeNamedItem
in interfaceNamedNodeMap
- Parameters:
name
- ThenodeName
of the node to remove.- Returns:
- The node removed from this map if a node with such a name exists.
- Throws:
DOMException
- NOT_FOUND_ERR: Raised if there is no node namedname
in this map.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly.
-
item
Returns theindex
th item in the map. Ifindex
is greater than or equal to the number of nodes in this map, this returnsnull
.- Specified by:
item
in interfaceNamedNodeMap
- Parameters:
index
- Index into this map.- Returns:
- The node at the
index
th position in the map, ornull
if that is not a valid index.
-
getLength
public int getLength()The number of nodes in this map. The range of valid child node indices is0
tolength-1
inclusive.- Specified by:
getLength
in interfaceNamedNodeMap
-
getNamedItemNS
Retrieves a node specified by local name and namespace URI.
Documents which do not support the "XML" feature will permit only the DOM Level 1 calls for creating/setting elements and attributes. Hence, if you specify a non-null namespace URI, these DOMs will never find a matching node.- Specified by:
getNamedItemNS
in interfaceNamedNodeMap
- Parameters:
namespaceURI
- The namespace URI of the node to retrieve.localName
- The local name of the node to retrieve.- Returns:
- A
Node
(of any type) with the specified local name and namespace URI, ornull
if they do not identify any node in this map. - Since:
- DOM Level 2
-
setNamedItemNS
Adds a node using itsnamespaceURI
andlocalName
. If a node with that namespace URI and that local name is already present in this map, it is replaced by the new one.- Specified by:
setNamedItemNS
in interfaceNamedNodeMap
- Parameters:
arg
- A node to store in this map. The node will later be accessible using the value of itsnamespaceURI
andlocalName
attributes.- Returns:
- If the new
Node
replaces an existing node the replacedNode
is returned, otherwisenull
is returned. - Throws:
DOMException
- WRONG_DOCUMENT_ERR: Raised ifarg
was created from a different document than the one that created this map.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly.
INUSE_ATTRIBUTE_ERR: Raised ifarg
is anAttr
that is already an attribute of anotherElement
object. The DOM user must explicitly cloneAttr
nodes to re-use them in other elements.
HIERARCHY_REQUEST_ERR: Raised if an attempt is made to add a node doesn't belong in this NamedNodeMap. Examples would include trying to insert something other than an Attr node into an Element's map of attributes, or a non-Entity node into the DocumentType's map of Entities.
NOT_SUPPORTED_ERR: Always thrown if the current document does not support the"XML"
feature, since namespaces were defined by XML.- Since:
- DOM Level 2
-
removeNamedItemNS
Removes a node specified by local name and namespace URI. A removed attribute may be known to have a default value when this map contains the attributes attached to an element, as returned by the attributes attribute of theNode
interface. If so, an attribute immediately appears containing the default value as well as the corresponding namespace URI, local name, and prefix when applicable.
Documents which do not support the "XML" feature will permit only the DOM Level 1 calls for creating/setting elements and attributes. Hence, if you specify a non-null namespace URI, these DOMs will never find a matching node.- Specified by:
removeNamedItemNS
in interfaceNamedNodeMap
- Parameters:
namespaceURI
- The namespace URI of the node to remove.localName
- The local name of the node to remove.- Returns:
- The node removed from this map if a node with such a local name and namespace URI exists.
- Throws:
DOMException
- NOT_FOUND_ERR: Raised if there is no node with the specifiednamespaceURI
andlocalName
in this map.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly.- Since:
- DOM Level 2
-
